Douglas Adams certainly continues the tradition of granitic British uncompromise with regards to tea, from George Orwell's instructions on holding steady during wartime rationing to Dr. Muriel Bristol's insistence that the order of milk vs. tea addition to the cup was of cardinal importance (thus, legendarily, leading to a new branch of statistics) to sir Edmond Hillary's famous lament about weak tea on Mt. Everest. But he doesn't say what to do at altitude. Neither does the following text (not Adams') at the cited website:
Simple enough but I have a question; one I think Douglas Adams would appreciate. The essential element in making that proper cup is that the water must be boiling. Now Douglas was a Brit, and he lived at sea level, and therein lies the problem. I live in Utah approximately 4500 feet (1372 meters) above sea level and since altitude has a definite effect on the temperature at which water boils there is a problem. Water boils at 212 degrees Fahrenheit (100 Celsius). For each increase of 500 feet (152 meters) of altitude the Fahrenheit temperature at which water boils goes down 1 degree. That means in my kitchen water boils at 203 degrees Fahrenheit (95 Celsius). Boiling as Douglas insists it must, but certainly not the same boiling that occurs at sea level. Does this mean I will never experience a proper cup of tea in Sandy Utah? I wonder if this applies to my coffee. Would anyone care to offer a solution to this problem?
My first solution was a literal solution: put the sugar in the kettle instead of the cup, raising the boiling point. But I found that, if I got all my constants right, one teaspoon of sucrose in a six fluid ounce cup of tea will raise the boiling point by about .07 degrees Fahrenheit, accounting for only a 33-foot ascent. Not much. (Calculations, which may well be wrong, available by request.) So we are still left with a hyperbaric chamber or nothing. Or green tea, of course. The market is now ripe for altitude-specific blends, which should of course come with topographic maps showing where they should be steeped with boiling water (or not steeped at all).
